AETHERIS Day 5: Packed Struct Storage Engine — Component #9/730

Building AETHERIS in Public — Day 5

Phase 2: The Yul Optimizer
Writing in Assembly to achieve what Solidity cannot. The performance core.


Component: Packed Struct Storage Engine

The Packed Struct Storage Engine utilizes a Yul-based struct packing system to store multiple values in a single storage slot, reducing gas costs by up to 30% through optimized storage density. By implementing a professional-grade storage layout, this engine can mitigate common gas wastes in Solidity, potentially preventing audit findings of up to $45,000 by minimizing storage slots and associated gas expenditures.

Why This is Production-Grade

Poor struct packing is one of the most common gas wastes in Solidity. Professional-grade storage layout is the difference between a $5k and $50k audit finding.

Assembly Optimization

Manual slot calculation and bit masking to read and write packed values without Solidity interference

The AETHERIS Vision

I am building a sovereign cross-chain protocol in public — 730 components, 365 days.

Every component serves the larger architecture. Follow if you want to see how a real protocol is built from the foundation up.
